Why is everyone overhere only using the arranger the easy way?

Today i can

- play piano style and still have auto accomp...
- need my feet to controll my sa2 voice ( atleast 2 footswitches, preferably 3, and a vollune pedal )
- use the ensemble feature withouth harmony and play 4 different instruments at the same time
- program my own styles, and connect a unit with 8 pods ( and sound just like those trance deejays do)
- sing along my playing..
- program my own sounds

Anyway, in my vision as a former organ player that transfered to a piano style, there is no room anymore for basspedals, but there is allways the need for 61 more keys.. And lots of realtime controllers...

I would love to see the next arranger have a few freely assignable pods...
